SPECIFICATION forming part of Letters Patent No. 608,981, dated August9, 1898; Application filed J'anuarylQ, 1897. Renewed June 3, 1898.Serial No; 682,505. (No model.)

To all whom it may concern:

Be it known that I,JOHN GO0D,of New York, (Far Rockaway,) in the countyof Queens and State of New York, have invented a new and usefulImprovement in Feeding Apparatus for Machinery for Preparing FibrousMaterials for Spinning, of which the following is a specification.

The improvement which is the subject of this invention is moreespecially applicable for the feeding sisal and other kinds of hemp thefibers of which are of considerable length, audit is applicable toany,machines"'such, for example, as spreading and drawing machines inwhich such fibers are subjected to the operation of devicescomprisingpinsby which the said fibers are subjected to a combing or hacklingoperation.

An apparatus embodying the said improvement consists of a tablecomprising bars armed with pins, means of 'moving the said table in onedirection, a fiber-feedin g carriage, and means for moving the saidcarriage back and forth over the said table for the purpose ofdepositing the fibers thereon in layers one upon another, with the'endsof the fibers of each layer lapping thoseof the layers above and belowthem; and the said improvement consists in certain combinationshereinafter described and claimed, of which such table and carriageconstitute elements;

In the accompanying drawings, Figure 1 is a side View of a feedingapparatus embody ing my invention. f-Figrfl represents a centrallongitudinal vertical section, andFig. 3 a plan View of the same, Fig.4," a side view showing some of the details on a larger scale than Fig.1.

Similar letters and numerals of reference designate corresponding partsin all the figures.

A is the framing on or in which arethe bearings for the shafts a b,which carry the wheels 0 d, on which run the endless chains 13, whichcarry the transverse bars 6, which are armed with gill-pins "f; Theseshafts, chains, wheels, bars, and pins may be of any known or suitableconstruction such as is common to spreading and drawing machines,

and they are represented of well-known con of fibrousmaterials'such asstruction, the bars in the upper run of the chains forming a platform ortable from which the pins f project upward. The said chains and thetrain of bars and pins are to receive motion from any suitable source ofpower.

on the sidesof the framing A are ways G, which extend from pointsforward of the chain-wheels d backward some distance beyond the rear ofthe said chains, the said ways being parallel both vertically andlaterally with the table or platform constituted by the straight upperrun of the said chains and their bars 6 and pins f. On these ways G runa carriage D, in which is mounted the axle E of a reel or lantern-wheelE, which extends across thechains B. The height of this reel above theways and the spacing of its rungs 25 are such that the rungs will enterbetween the rows of pins in the bars of the upper run of the chainsB'and press upon a bed of fiber imposed'on the said bars, and that asthe earriage D is'moved back and forth on the ways the reel maybe causedto rotate by the contact of its rungs with the said pins. The axle 8o Eof the reel is so mounted in its hearings in the carriage that the reelmay be capable of a suffioient rise and fall to accommodate itself tothe thickness of the bed of fibers on the bars 6. The mechanism forproducing the backward-and-forward movement of the carriage to roll thereel over the pins f may be of any suitable kind. Of the mechanism whichI have represented for that purpose,

left hand threaded endless His a right and screw the shaft or core ofwhich is fitted to turn freely, but confined. lengthwise, in fixedbearings u on the frame A. This screw, which is parallel with the waysG,isj fitted with a switch-nut I, which, by the continuous rota tion ofthe screw inone direction, is caused to run back and forth upon theright :and left hand threads. The said nut I is connected with thecarriage D by a rod J. The screw II is represented as'furnished with apulley mo 4), through which it is to be driven by a rap idlyrunning belt10. The speed at which the The carriage D is represented as having a'counterbalance-weight K connected with it by a cord K running overguide-pulleys K This counterbalance is only rendered necessary when thechains and the carriage D are arranged to run at an inclination, asshown in the drawings, the counterbalance counteracting the tendency ofthe carriage to run downward; but this inclination of the chains and bedis not essential tomy invention, which would be just as well applicablein connection with chains the upper runs of which were horizontal, inwhich case the carriage would run horizontally.

Just behind the reel E there is arranged upon the carriage D a risingand falling or tilting feed-board F, which constitutes the principalfeature of the present improvement. This feed-board is pivoted at itslower and forward end by a shaft F, which works in bearin gs 10 on thesides of the carriage. The said shaft F serves no other purpose than asa pivot for the upward movement of the feedboard to the nearly uprightposition shown in full outline in Figs. 1 and 2 and its downwardmovement to the nearly horizontal position shown in dotted outline inthe same figures, in which latter position it is supported upon a rest Faffixed to the carriage. In either of these positions the lower or frontend of the feed-board is high enough to pass over the pins f. A littleway behind the said shaft F a rock-shaft R is arranged in bearings 11 onthe sides of the carriage D. This rock-shaft carries an arm R, on theend of which is an antifriction-roller 12, upon which the feedboard Fbears, the purpose of the said rockshaft and arm being to tilt thefeed-board from the rest F to the nearly upright position, and therebyto deposit upon the pin-bars the bunches of fibers which are placed uponthe feed-board while it is in the nearly horizontal position. The saidrock-shaft R is furnished outside the frame with a spur-gear 13, (seeFigs. 1, 3, and 4,) which gears with a spurgear 14, turning loosely on afixed stud 15, secured on the top of the carriage. On the same stud 15there is loosely arranged a tappet 16, which when turned in thedirection of the arrow shownin Fig. 4, by running against a fixedstop-pin 18 on the side of the framing A, is brought into action on atappet-piece l7, affixed to the spur-gear 14, and turns the gear 14 inthe same direction and so causes the latter to turn the gear 13 and therock-shaft R in the opposite direction, and thereby to raise the arm Ragainst the feed-board and so tilt the said board to the nearly uprightposition.

The tappet-piece 17 is extended backward in the form of a guard 17 tooverlap the tappet 16 and protect it from lateral displacement. Therock-shaft R is furnished outside of the framing A with an arm, on whichis a counterbalance R to the weight of the arm R and the feed-board. Therest F is furnished at the top with an india-rubber cushion 22 toprevent any violent concussion of the feed-board when it drops thereon.

This feeding apparatus is placed behind any suitable device for combing,spreading, or drawing fibers-as, for example, an endless train ofpin-armed bars-and so placed its operation is as follows: An attendanttakes in his hands a bunch of raw fiberssuch, for example, as thebunches in which the raw hemp comes in bales to the market-and while thefeed-carriage D, with the feed-board F and reel E, is moving forward inthe direction of the arrow 19, (shown in Figs. 1 and 2,) the feed-boardbeing'in its nearly horizontal position on the rest F he places thefibers lengthwise along the board and spreads them to some extent acrossthe same and leaves them there. As long as the carriage continues movingforward or in the same direction with the upper run of the bars 6 andpins f the feed-board remains in this position, the tappet 16 swingingback and passing freely over the stop 18 on the framing withoutproducing any action on the gear 14; but after the carriage has movedbackward in the direction of the arrow 20 a very short distance thetappet 16, coming in contact with the pin 18, is turned toward andagainst the tappet-piece 17 on the said gear 14, and so, as the carriagecontinues moving backward, turns the said gear 14 in the direction ofthe arrow shown upon it in Fig. 4, thereby turning the gear 13 and therock-shaftR in the opposite direction and raising or tilting thefeed-board. While the feed-board is thus'being tilted the fibers areshot or run freely by their own weight down the feed-board and so bringtheir forward ends under the reel E, which, being turned in thedirection of the arrow shown upon it in Figs. 1 and 2, by its rungscoming in contact with the pins f as the backward movement of thefeed-carriage continues, is caused to draw the fibers from the board andto deposit them upon the pins f. When the carriage has run some distancebackward, the tappet 16 escapes from the pin 18, and the feedboard dropsagain to the rest F but this does not interfere with the drawing of thefibers therefrom and depositing them as hereinabove described. Thisoperation is repeated during every movement of the carriage backward,and the successive bunches of fiber are thus superposed in severallayers upon and between the pins f and upon the bars 6; but

as the chains B, with the said bars and pins, are continuously movingforward at a speed much slower than that of the carriage the severallayers are superposed each some distance behind the next layer below,and so the ends of the fibers of the several layers overlap or breakjoint With each other, as indicated at 6 7 8 9 in Fig. 2. Thus in thevery act of feeding the raw material it is so placed as to effect in avery considerable degree the essential object aimed at in all machineryfor preparing fibrous materials-viz., the distribution of the ends ofthe fibers at numerous points in the length of the lap or sliver to beproduced.

What I claim as my invention is- 1. The combinationof a table comprisingbars armed With pins, means for moving said table in one direction, acarriage and means for moving the same back and forth over said table, atilting feed-board on said carriage, and means for tilting saidfeed-board, sub stantially as herein described.
